mu_C = 1.6389; // Refractive index index of material
mu_F = 1.7168; // Refractive index index of material
Lambda_C = 6563e-008; // Wavelength of C Sodium light, Angstorm
Lambda_F = 4861e-008; // Wavelength of F Sodium light, Angstorm
Lambda = 5e-05; // Wavelength of light, cm
t = 3; // Length of base of a flint glass prism, cm
// Since the resolving power of a spectrometer is given by Lambda/d_Lambda. Thus
D = (mu_F - mu_C)/(Lambda_C - Lambda_F); // Dispersion of material of the prism
d_Lambda = Lambda/(t*D); // Resolving power of a prism
printf("\nThe smallest difference of wavelengths resolved by the flint glass prism = %4.2f angstrom", d_Lambda/1e-008);
// Result
// The smallest difference of wavelengths resolved by the flint glass prism = 0.36 angstrom
// The answer is given wrong in the textbook
